Why do the texture I baked with an external application and not the Substance Bakers look incorrect in Substance Painter ?
There is no immediate solution to this problem as many factors can contribute to the problem :
- Verify that the normal format between the Substance software and the external application is the same. OpenGL is [X+, Y+, Z+] and DirectX is [X+, Y-, Z+]
- Verify that the mesh has been triangulated before baking and importing it in the Substance software. See this page for more information.
